Abstract

Background: Since it is critical to understand the anatomy of the coronary arteries
and the anastomoses between them in Akkaraman sheep, the coronary arteries
will be examined using a plastic injection and corrosion technique.
Materials and methods: In our investigation, researchers used 20 Akkaraman
sheep’s hearts collected from slaughterhouses in and near Kayseri, and hearts
from animals aged 2–3 years were included. The anatomy of the coronary arteries
of the hearts was studied by plastic injection and corrosion method. The macroscopically
examined patterns of the excised coronary arteries were photographed
and recorded.
Results and Conclusions: This approach indicated arterial vascularisation of the
heart in sheep, with a. coronaria dextra and a. coronaria sinistra developing from
the commencement of the aorta. It was determined that a. coronaria sinistra,
after leaving the initial part of the aorta, proceeds to the left and divides into two
branches called r. interventricularis paraconalis and r. circumflexus sinister, forming
a right angle between them, immediately after reaching the sulcus coronarius.
Anastomosis of the branches of r. distalis atrii dextri with the branches of r. intermedius
atrii dextri and r. ventriculi dextri; anastomosis of a thin branch separated
from r. proximalis atrii sinistri with the branch of r. proximalis atrii dextri running in
the initial part of the aorta; anastomosis of r. distalis atrii sinistri with r. intermedius
atrii sinistri were detected. In one heart, the r. septalis protruded roughly 0.2 cm
from the beginning of a. coronaria sinistra.
